Rotork’s IQ intelligent valve actuator range the best just got better Rotork’s tried and tested range of IQ intelligent electric valve actuators is now further enhanced - retaining legendary features such as Rotork’s unique double sealing system and ‘non-intrusive’ infrared commissioning capability by the addition of the IQT dedicated quarter-turn actuator.

sealing with a watertight enclosure coupled with infra-red set-up and comprehensive protection systems have come together to make IQ the world leader in reliable valve operation. Gain peace of mind and minimise maintenance costs with fit and forget IQ technology. Simple commissioning

The IQT (IQ quarter-turn) is the result of ongoing commitment to product development at the leading edge of new technology. The Rotork IQ now delivers a complete range of actuators suitable for most quarter and multi-turn applications that require control and indication flexibility, offering end users ever higher standards of performance build quality and overall value.

Simple, safe and rapid non-intrusive commissioning with infra-red control. Actuator settings such as torque levels, position limits, control and indication functions can be accessed and adjusted using the “point and shoot” IQ Setting Tool. The supplied, intrinsically safe (IS) tool is unique to Rotork and allows non-intrusive actuator set-up whatever the environment, power on or power off.

The IQ continues to offer all the key benefits which have made it a world leader including:

IQ - simply unmatched for reliability

Position measurement Reliable process control depends on accurate positioning of the valve at end of travel and for fluid control, mid travel. The patented IQ non-contacting position measuring system is the most simple yet devised for actuator control. With only one moving part, the resolver converts output centre column rotation into an electronic signal which is then compared to position limits stored within a safe, non volatile memory. IQT speed control By use of motor control technology proven in the AQ range over 20 years and now integrated with the IQ “actuator on a chip” the output speed of the IQT can be adjusted without affecting the torque output.

Protection - the key

Non-intrusive - sealed for life

Vast experience in the application of electric actuators has enabled Rotork to lead the world in actuator ingress protection. Situated in environments ranging from desert to tundra, offshore to underground, where flooding, humidity, extremes of heat and cold, ultra violet and corrosive atmospheres are normal, actuators have to perform unfailingly. Rotork understand that the most important factor in the reliability of an actuator is protection from the environment - in simple terms, the enclosure.

IQ covers need not be removed for site commissioning. All settings and adjustments are made using the supplied infra-red Setting Tool, including speed setting for the IQT. After assembly in the controlled environment of our manufacturing facilities, air exchanges are eliminated all internal components are completely protected for life. Non-intrusive control selectors mean there are no moving shafts penetrating the control enclosure. Reliability through simplicity

Double sealed for double protection The IQ enclosure is rated IP68 7 metres for 72 hours, NEMA 4/4X/6. It is completely watertight and dusttight and does not “breathe”. The Rotork Double Seal system ensures protection of internal components since they are separated from the cable gland and terminal compartment by a watertight terminal block. Protection is maintained during site hook-up when terminal covers are removed and is independent of cable gland sealing. 4

The IQ combines simplicity of design while extending specification and performance. Torque measurement An actuators ability to reliably and accurately determine the force applied in operating a valve is fundamental in providing valve and actuator protection. The IQ range uses tried and tested technology, proven in industry. Accurate, repeatable torque measurement is achieved independent of variations in frequency, voltage and temperature.

IQ - big on intelligence

Actuator display The IQ incorporates a unique liquid crystal display developed specifically for actuator indication. Large segments allow easy, distance viewing of valve position, torque and diagnostic screens. A unique, diffused LED backlighting system provides high visibility in all light conditions. The LCD display is supplemented with position indication lights, green, yellow and red.

Looking at an example of a close valve command, by applying a signal to the remote close input and close interlock input simultaneously the actuator will operate and close the valve. If only one signal is applied, or a signal is lost, the actuator will failsafe by staying put or stopping. When conditional remote control is configured, the interlock inputs are not required for local operation.

Indication back up

Data logging

Rotork recognise the need for local and remote position indication at all times, even when the actuator is powered down. The IQ incorporates a battery to maintain and update position indication when the main power is switched off. The battery also supports power off data logging and commissioning.

Every IQ includes an on board data logger. The data logger captures and stores valve, actuator and control signal operation and status data:

Set-up Infra-red set up, adjustment and review using the supplied, intrinsically safe IQ Setting Tool allows users access to the configuration of the actuator using the convenient actuator liquid crystal display. On screen diagnostic icons

Statistics

Log data is time and date stamped and can be analysed by playing back in “real time” or on an event by event basis.

Four dedicated alarm icons are incorporated into the LCD display giving clear indication of valve, control system and actuator alarms.

The data logger is accessed via the IrDA™ interface to compatible devices, see below. Data logger data can be analysed with IQ-Insight PC based software, described in detail on page 8.

Help screens

IrDA™ communication (IQ-Insight)

Nine help screens can be accessed with the IQ setting tool allowing real time, grouped analysis of control signal status, valve and actuator status and indication status.

IQ supports IrDA™ compatible communication. IQ configuration and data logger files are accessed via the infra-red port non-intrusively. Data exchanges are via IrDA™ with compatible Personal Digital Assistants (PDAs), note books or PCs. IQ-Insight PC software provides the interface with the actuator and its on-board data logger.

Full security, full protection

Syncrophase prevents valve damage through incorrect wiring Rotork’s unique ‘Syncrophase’ automatic phase rotation correction prevents valve damage through incorrect wiring by ensuring that the IQ three-phase motor is always presented with the correct phase rotation of the power supply. Single phasing protection Also developed to control motor overheating, IQ electronics constantly monitor all three phases of the power supply. Should one or more phases be lost the control circuit is prevented from energising the contactors. Local and remote alarm signals of incomplete supply are offered as standard features. Motor protection when valve jams Should a valve jam, the IQ motor is prevented from overheating by a logic circuit which trips the contactor when there is no movement within seven seconds of a start signal. IQT uses a 24 volt DC motor. For single and 3 phase* supplied actuators the motor supply is internally provided via a transformer - rectifier (24 volt DC supplies - rectifier only). IQT will always run in the correct direction irrespective of supply type and connection. On loss of one or more of the utilised phases (or DC supply pole) the IQT actuator will stop.

6

IQ thermostatic protection Two thermostats embedded in the motor windings directly sense temperature, tripping the actuator control circuit in the event of overheating. IQT thermostatic protection Two thermostats are embedded in the toroid transformer windings providing comprehensive motor power module protection. Auto self test and diagnosis (ASTD) Each time the actuator is powered up, its vital operational circuits automatically self test to ensure correct operation. In the unlikely event that a fault is diagnosed the information is automatically presented using the display icons. At the same time, actuator operation can be inhibited to enable site investigation. Instant reversal protection An automatic time-delay circuit avoids the shock loads which may cause unnecessary wear to valve stems and gearboxes when an actuator is ordered to reverse direction ‘instantaneously’. The circuit also limits current surges through the contactor.

* Actuator utilises 2 phases only - refer to circuit diagram.

Standard specification

3 Introduction IQ actuators are self contained units for local and remote electrical operation of valves. Comprising an electric motor, reduction gearing, reversing starter with local controls, turns and torque limitation with electronic logic controls and monitoring facilities, all housed in a double-sealed watertight enclosure to IP68 7 metres-72 hours, NEMA 4, 4X and 6. All torque and turns settings and configuration of the indication contacts are effected using the non-intrusive, hand held infra-red, IQ Setting Tool, which is included with each order. The following specification covers standard features and available optional features. Options selected must be specified with enquiry.

4 Mechanical 4.1 Enclosure and ambient temperatures All IQ actuator hazardous and nonhazardous area enclosures are built to a watertight standard. Through the use of non-intrusive commissioning and site adjustment using the supplied infra-red IQ Setting Tool, the hermetic, factory-sealed enclosure protects internal components for life as covers never need removing. The terminal compartment is sealed from other areas by the Rotork double seal, maintaining watertight integrity even during site connection. Actuators are available with the following enclosure types for which the ambient working temperature ranges are stated. Where option temperatures are indicated, changes to some actuator components are required and therefore the temperature requirement must be specified. Hazardous area approvals for other country standards are available, please apply to Rotork. The IQ range is built in accordance with the following standards:

For details please contact Rotork. 4.2 Valve/actuator interface The range of IQ actuators is available with mounting base and output drive couplings conforming to international standard ISO 5210 or USA standard MSS SP-102. IQT actuators are available with mounting base and output drive couplings conforming to ISO 5211 or US standard MSS SP-101. Applications for which the various types of couplings have been designed are outlined on pages 20-22 4.3 Handwheel Handwheels are provided to allow manual operation of the valve during electrical power interruption. IQ10 - IQ40 Direct acting top mounted handwheel. Option: side mounted geared handwheels.

IQ70 - IQ95 Side mounted geared handwheel. Option: alternative gear ratios. IQT all sizes. Side mounted geared handwheel. During electric operation of the actuator the handwheel is mechanically disengaged from the drive. To engage handwheel operation, the hand/auto selection lever is depressed and released after which handwheel operation remains selected. When electrical operation takes place, the actuator will automatically return to motor drive without lever or handwheel kickback. The hand/auto selection lever incorporates a facility for locking in the hand or auto positions using a 6mm diameter hasp padlock (not supplied by Rotork), preventing engagement of motor drive (locked in hand) or engagement of handwheel drive (locked in auto). Emergency disengagement of motor drive can be selected by depressing and holding the lever during electric operation.

4.4 Lubrication IQ and IQT actuators are factory filled for life with premium quality gear oil specified as SAE 80/90 EP for IQ and Dextron 2 for IQT. Oil lubrication out-performs grease over the IQ temperature range -30°C to +70°C, with none of the problems associated with grease such as separation and tunneling. Rotork have used this same grade of lubricating oil for 40 years. Lubrication options Food grade lubricant IQ and IQT actuators may be supplied with the gearcase filled with Hydra Lube GB Heavy food grade lubricant. This lubricant is a synthetic nonaromatic hydrocarbon mixture with PTFE and other additives. It does not contain chlorinated solvents. Grease used in assembly and thrust bearings is Hydra Lube WIG Medium-NLGI-123. Extreme temperature service Where actuator service requires operation outside of -30°C to +70°C alternative lubricants are available, please apply to Rotork.

4.5 Finish All IQT and IQ actuators up to size IQ35 are finished in polyester powder coating, colour silver grey. Actuators size IQ40 and above are finished in air-dried urethane reinforced synthetic alkyd resin colour, silver grey. For full specification of paint finish see publication E151E. Finish options Colour: Other colours may be specified, please apply to Rotork. Offshore: 2 pack epoxy coatings are available for extreme environmental conditions, please apply to Rotork.

5.1 Power supplies

Available for standard single-phase voltages: 50Hz: 110, 115, 120, 220, 230 and 240 volts 60Hz: 100, 110, 115, 120, 208, 220, 230 and 240 volts

IQ and IQT actuators are suitable for operation with the following three phase, three wire power supplies:

IQD and IQT DC

5.2 Control Local control Non-intrusive selectors are provided on the actuator electrical control cover, one for Local/Stop/Remote selection, pad-lockable in each position, and the other for Open/ Close control. Controls may be rotated to suit actuator orientation. Local control may be selected to operate using the supplied IQ Setting Tool. The Setting Tool incorporates dedicated open, stop and close buttons and will operate over a nominal distance of 0.75 metres from the display window. 25


Local control option Vandal resistant Selectors removed, indication window with removable cover, control of local, stop and remote selection and local open and closed control is via the supplied IQ Setting Tool. Remote control There are six control inputs for remote control: Open, closed, stop/maintain. Emergency shut down (ESD). Open interlock and closed interlock. Control can be connected for maintained or push to run, (inching) control.ESD signals must be derived from a stayput contact. For more information refer to publication E120E. Control inputs are opto-isolated interfaces with a surge immunity of 2kV. Control is positive switching negative earth, internally fed from the actuator 24V DC customer supply or from external supplies within the ranges 20-60V AC or DC or 60-120V AC. ESD can be configured off, active high or active low, to close or open the valve, with or without automatic motor thermostat bypass*. ESD will override any local or remote signals that may be active. If required ESD can be configured to override local stop, interlocks or the optional interrupter timer. The ESD input operates from a separate common allowing isolation between the ESD control system and operational control systems. *Bypassing the motor thermostat will invalidate hazardous area certification.

Remote control can be configured so that the open signal and open interlock (or closed signal and closed interlock) can be combined to form a remote open (or closed) signal that can detect single faults. When configured, interlocks will not be active during local control. For more information refer to publication E120E. 26

Remote control options Negative switching For remote control systems where the negative pole of the remote control circuit supply is switched. External control circuit supplies For control with supplies in the range 60 - 125V DC and 230V AC an alternative control circuit option is available. Analogue Proportional Control The Rotork Folomatic proportional controller enables the actuator to automatically position a valve in proportion to an analogue current, voltage or potentiometric signal. Signal ranges: 0-5, 0-10, 0-20 or 4-20mA. 0-5, 0-10 or 0-20V. Positioning can take place over the whole valve stroke or if required, a set portion of stroke. By incorporating a remote manual/remote auto control selector in the control scheme, proportional control can be overridden allowing standard remote control operation to take place when manual intervention is required (see above). The Folomatic can be configured to failsafe stayput, open or closed on loss of analogue signal.

Hydraulic shock/surge protection IQ Where the operating time of the valve must be increased to prevent hydraulic shock or water hammer, or to prevent surges, the Rotork Interrupter Timer option can be included. Pulsed operation with independently adjustable on and off time periods in the range 1-99 seconds can be selected to operate over any portion of the closing or opening valve stroke, effectively reducing valve speed. On/Off time period range may be extended when configuration is carried out with the IQ-Insight PC tool. The interrupter timer is active for both local and remote control. Hydraulic shock/surge protection IQT The IQT actuator allows the output speed to be adjusted with the Setting Tool. Refer to performance summary, page 19. Speed control over 4:1 ratio is available and settable non intrusively. The IQT also includes the Interrupter Timer option (as above) for extended operating times.

5.3 Indication, monitoring and data logging Local A back-lit liquid crystal display gives digital indication from fully open to fully closed in 1% increments. Three LED’s coloured red, green and yellow for indication of open, close and intermediate positions respectively are also provided. The display includes four icons for rapid diagnosis of valve alarm, actuator alarm, control system alarm and actuator battery status. With the supplied IQ Setting Tool, actuator torque plus position can be displayed allowing the valve torque against position to be monitored in real time. Help screen diagnosis is available for monitoring valve, actuator and control system status. The local display can be rotated to suit actuator orientation. LED colours can be reversed. Please specify with order. Remote Four latching volt free contacts, S1, S2, S3 and S4 are provided each independently configurable using the supplied IQ Setting Tool to signal one of the following: Valve Position fully open, fully closed or intermediate positions (0-99% open).

IQT The IQT power module consists of a torroid power transformer with a fast acting micro controller based, intelligent switch mode motor drive. Customer remote control supply is an isolated 24V DC rated at 5W or an optional nominal 110V AC supply rated at 20VA. 6.3 Control module IQ and IQT Incorporating a single integrated circuit, hard-wired logic control for the actuator together with infra-red (IrDA) interface for external nonintrusive settings and interrogation by IQ-Insight configuration and data logger viewer PC tool. On board data logger records operational data, valve torque/position profiles and statistical information, all time and date stamped.

IQS Single Phase Capacitor start/run squirrel cage induction motor. IQDC: Permanent magnet, low inertia design.


IQD Direct Current Permanent magnet, DC motor incorporating thermostatic protection.

Position setting range: 2.5 to 100,000 turns, with a maximum angular resolution to 7.5° of actuator output center column.

IQT 24V DC permanent magnet, low inertia motor. The IQT motor has a proven 20 year record in valve actuators. 6.2 Power module IQ The power module incorporates a mechanically and electronically interlocked reversing contactor starter*. The control supply transformer, fed from two phases of the incoming power supply, provides internal control circuit supplies and an isolated, nominal 24V DC customer supply rated at 5W for actuator fed remote control circuits. The Rotork Syncrophase circuit incorporates phase rotation correction and lost phase protection.

IQ Position and torque are adjustable as follows:

IQT Torque setting: 40% to 100% rated torque. Torque sensing is derived from drive current sensing and digital filtering. Position setting range: Limits are factory set to 90° stop bolt positions (nominal). Limit setting range: 10° to 1800°. Maximum angular resolution to 0.1°. The IQT actuator speed range can be configured with the IQ Setting Tool. Output torque for the IQ, is obtained via the direct measurement of wormshaft thrust reaction under load and is independent of voltage, frequency and temperature fluctuations.

For the IQT the output torque is measured using the motor current. Torque off during unseating or during starting/reversing in mid travel against high inertia loads can be inhibited. The jammed valve protection circuit de-energizes the motor if no movement occurs after a few seconds from receipt of a signal to open or close. When power to the actuator is isolated, all settings are retained in an EEPROM. In the event of manual operation of the valve during isolation or loss of the power supply a battery provides power to the internal position-monitoring transmitter to update the valve position data in the EEPROM. The battery also drives the LCD display, without backlighting, and the four latching contacts S1-S4 while the power to the actuator is not available. Based on a typical application the minimum battery life is 5 years. Infra-red setting is also available with main power off. 6.5 Conduit entries, terminals and wiring IQ actuators Three threaded conduit entries are provided tapped: 1 x 11/2 and 2 x 1” ASA NPT.
